What this book covers

Chapter 1, Metrics That Matter, explains the theory behind lean management and how you can measure performance and cultural change. It looks into developer productivity and why this is so important to attract talent and achieve outstanding customer satisfaction.

Chapter 2, Plan, Track, and Visualize Your Work, is about work insights: accelerate your software delivery performance by applying lean principles. You’ll learn how to plan, track, and visualize the work across your teams and products using GitHub Issues, Labels, Milestones, and Projects.

Chapter 3, Teamwork and Collaborative Development, explains the importance of collaborative development of software and how GitHub can be used for collaboration across teams and disciplines.

Chapter 4, Asynchronous Work: Collaborate from Anywhere, explains the benefits of asynchronous ways of working and how you can leverage them for improved and shared responsibilities, distributed teams, better quality, and cross-team collaboration. It shows how you can use GitHub Mobile, Microsoft Teams, Slack, and GitHub Pages, Wikis, and Discussions to collaborate from any location and any device.

Chapter 5, Influence of Open and Inner Source on Software Delivery Performance, describes the history of free and open source software and the importance it has gained over the recent years and in the context of cloud computing. It will teach you how to leverage open source to speed up your software delivery. Moreover, it will explain how open source practices applied to inner source will help you transform your organization, and the impact open and inner source can have on your in- and out-sourcing strategy.

Chapter 6, Automation with GitHub Actions, explains the importance of automation for quality and speed. It introduces you to GitHub Actions and how you can use them for any kind of automation – not only continuous delivery.

Chapter 7, Running Your Workflows, explains how you can tackle hybrid-cloud scenarios or hardware-in-the-loop tests using the different hosting options for the GitHub Actions workflow runners. It shows how to set up and manage self-hosted runners.

Chapter 8, Managing Dependencies Using GitHub Packages, describes how you can use GitHub Packages and semantic versioning together with GitHub Actions to manage dependencies between your teams and products.

Chapter 9, Deploy to Any Platform, shows how you can easily deploy to any cloud and platform with simple hands-on examples for Microsoft Azure, AWS Elastic Container Service, and Google Kubernetes Engine. It shows how you can perform staged deployments with GitHub Actions and how to use Infrastructure as Code to automate the provisioning of your resources.

Chapter 10, Feature Flags and the Feature Lifecycle, explains how Feature Flags – or Feature Toggles – can help you to reduce complexity and manage the lifecycle of features and your software.

Chapter 11, Trunk-Based Development, explains the benefits of trunk-based development and introduces you to the best Git workflows to accelerate your software delivery.

Chapter 12, Shift Left Testing for Increased Quality, takes a closer look at the role of quality assurance and testing on developer velocity and shows how you can shift left testing with test automation. The chapter also covers testing in production and chaos engineering.

Chapter 13, Shift Left Security and DevSecOps, takes a broader look at the role of security in software development and how you can bake security into the process and practice DevSecOps, zero-trust, and how you can shift left security. The chapter looks at common attack scenarios and how you can practice security and create awareness using attack simulations and red team | blue team exercises. The chapter also introduces you to GitHub Codespaces as a secure development environment in the cloud.

Chapter 14, Securing Your Code, describes how you can use GitHub Advanced Security to eliminate bugs, security, and compliance issues by performing static code analysis with CodeQL and other tools, successfully manage your software supply chain with Dependabot, and eliminate secrets in your code base using Secret Scanning.

Chapter 15, Securing Your Deployments, shows how you can secure deployments to your environments and how you can automate your complete release pipeline in a secure, compliant way to also meet regulatory requirements. The chapter covers Software Bills of Materials (SBoM), code and commit signing, dynamic application security testing, and security hardening your release pipelines.

Chapter 16, Loosely Coupled Architecture and Microservices, explains the importance of loosely-coupled systems and how you can evolve your software design to achieve this. The chapter covers microservices, evolutionary design, and event-based architectures.

Chapter 17, Empower Your Teams, is about the correlation of the communication structure of your organization and your system architecture (Conway’s law) and how you can use this to improve architecture, organization structure, and software delivery performance. It covers the two-pizza team, the Inverse Conway Maneuver, and a mono- versus multi-repo strategy for your code.

Chapter 18, Lean Product Development and Lean Startup, is about the importance of lean product management at a product and feature level. It shows how you can incorporate customer feedback into your product management, create Minimal Viable Products, and how you can manage your enterprise portfolio.

Chapter 19, Experimentation and A|B-Testing, explains how you can evolve and continuously improve your products by conducting experiments to validate hypotheses through evidence-based DevOps practices like A|B-testing. It also explains how you can leverage OKR to empower your teams to conduct the right experiments and to build the right products.

Chapter 20, GitHub: The Home for All Developers, explains how GitHub can serve as the holistic, open platform for your teams. It explains the different hosting options, pricing, and how you can integrate it in your existing toolchain.

Chapter 21, Migrating to GitHub, will discuss strategies to migrate from different platforms to GitHub and integration points for other systems. It explains how you can find the right migration strategy and how you can use the GitHub Enterprise Importer and Valet to perform the heavy lifting.

Chapter 22, Organize Your Teams, talks about best practices to structure your repositories and teams into organizations and enterprises to foster collaboration and facilitate administration. The chapter covers role-based access, custom roles, and outside collaborators.

Chapter 23, Transform Your Enterprise, puts all the pieces together. This book gives you a lot of tools that you can use to drive a successful transformation and to gain developer velocity. But only if all pieces are put together will the transformation succeed. The chapter will explain why many transformations fail, and what you should do to make your transformation a success.
